2.0 —Description

The HXP50-MECA hexapod is a parallel kinematic motion device thatprovides six degrees of freedom: X, Y, Z, pitch, roll, and yaw. Hexapods arewell known as effective solutions for complex motion applications thatdemand high load capacity and accuracy in up to six independent axes.Yet, they still have the image of being complex and highly priced. With theHXP50, Newport continues to introduce Hexapods that are not onlyaffordable but also extremely easy to use.

The HXP50-MECA is driven by six DC servo motor driven actuators withencoder feedback at the leadscrew nut, providing precise MIM, lowbacklash and fast speed. The quality of the actuators has obviously astrong impact on the overall motion performance of the HXP50-MECA, butof equal importance are the joints with which the actuators are attachedto the base and the moving top plate. With size and rigidity in mind, ourengineers came up with innovative spherical joints that are not only verysimple, but also enhance the stiffness of the hexapod.

The HXP50-ELEC controller accurately masters the synchronizedtransformations from Cartesian input coordinates to the motion of theHexapod legs. In addition, the HXP50-ELEC provides advanced featuresincluding instrument grade I/O's, hardware based input triggers, eventtriggers, high-speed on-the-fly data acquisition, fast TCP/IPcommunication, and integrated TCL programming language for on-boardprocesses. All these features improve accuracy and throughput, makingthe programmer’s life much easier.

The main differentiator of the HXP50-MECA, as with the other Newporthexapods, is the ability to program two pivot points represented by theTool and Work coordinate systems. The Tool CS moves with the top plateand the Work is stationary. Imagine a machine tool where one can adjustthe orientation of both the cutting tool and workpiece or in photonics, theoptical beam and the sample. Incremental displacements are possible ineither one in user-friendly Cartesian coordinates, and positions can beeasily switched from one system to the other by a function call or bynumerical input in the HXP's web site interface. These powerful functionsare a completely new way of mastering Hexapod motions without the needfor complex external coordinate transformations.

Absolute moves and positions aredefined in the work coordinatesystem. Incremental moves canbe done in the tool or in the workcoordinate systems.WORLD

4.1 Warnings on Controllers

Controllers are intended for use by qualified personnel who recognizeshock hazards and are familiar with safety precautions required to avoidpossible injury. Read the controller user’s manual carefully beforeoperating the instrument and pay attention to all written warnings andcautions.

WARNING

Disconnect the power plug under the following circumstances:

• If the power cord or any attached cables are frayed or damaged inany way.

• If the power plug is damaged in any way.

• If the unit is exposed to rain, excessive moisture, or liquids are spilledon the unit.

• If the unit has been dropped or the case is damaged.

• If you suspect service or repair is required.

• Whenever you clean the electronics unit.

CAUTION

To protect the unit from damage, be sure to:

• Keep all air vents free of dirt and dust.

• Keep all liquids away from the unit.

• Do not expose the unit to excessive moisture (85% humidity).

• Read this manual before using the unit for the first time.

WARNING

All attachment plug receptacles in the vicinity of this unit are to be ofthe grounding type and properly polarized.

Contact your electrician to check your receptacles.

WARNING

This product is equipped with a 3-wire grounding type plug.

Any interruption of the grounding connection can create an electricshock hazard.

If you are unable to insert the plug into your wall plug receptacle,contact your electrician to perform the necessary alterations to ensurethat the green (green-yellow) wire is attached to earth ground.

WARNING

This product operates with voltages that can be lethal.

Pushing objects of any kind into cabinet slots or holes, or spilling anyliquid on the product, may touch hazardous voltage points or short outparts.


7 EDH0324En1020 — 08/15

4.2 Connection

WARNING

Always turn the controller's power OFF before connecting to a strut.

Anytime prior to power-up, each strut must be connected with thesupplied cables to the corresponding 2 plugs located at the rear panel ofthe HXP50-ELEC controller. The SUB-D25 cable must be connected to theplug labeled “MOTOR”, the SUB-D15 cable to the plug labeled “ENCODER”.

WARNING

Each Hexapod strut label corresponds to the axis number of theHXP50-ELEC controller. This label is also indicated on connectors of thestrut.

4.3 Cables

Each Hexapod is equipped with cables terminated with SUB-D25Mconnectors for motors and SUB-D15M connectors for encoders. Thesecables are directly connected to the HXP50-ELEC.

There are two cables per strut: 12 cables total to connect to thecorresponding plugs on the controller.

6 SUB-D25F CONNECTORSFOR MOTOR CABLES

6 SUB-D15F CONNECTORSFOR ENCODER CABLES

EDH0324En1020 — 08/15 8


CAUTION

Numbering of axes is important for both motor and encoderconnections. A mismatch will cause fatal errors during initialization.

NOTE

On each connector, a sticker indicates the home preset and backlash onthe SUB-D25M connector, and the resolution on the SUB-D15Mconnector.

These parameters have to be set into the HXP50-ELEC controller foreach strut. This is done at our factory when the HXP50-MECA Hexapodis ordered with the HXP50-ELEC controller.

WARNING

The HXP50-MECA must be grounded via a threaded hole to avoidelectrical disturbances generated by ground loops.

WARNING

These cables are shielded correctly. For a correct operation, make sureto lock connectors (ground continuity provided by the cable).

WARNING

Keep the motor cables at a safe distance from other electrical cables inyour environment to avoid potential cross talk.
